Are All Mini Red Dot Sights Junk?

Below are my sighting-in experiences with three of them:



BURRIS FASTFIRE 3:

Mounted on a Ruger SR-556FB. Shooting off of a bench at 100 yards.

Several upward elevation adjustments did not produce any impact changes at all.

Windage only required a few clicks to the right. Unable to obtain a zero on the rifle.



VORTEX VENOM:

A.) Mounted on a Colt Gold Cup National Match Series 70. Shooting two-handed, unsupported at 25 yards.

Windage required major changes to the right. Able to obtain zero, but extremely close to running out of adjustment.

Elevation required just a few clicks upward. Windage and elevation adjustments were set back to their original, factory positions.


B.) Same sight was then mounted on a Smith & Wesson Model 586. Shooting two-handed, unsupported at 25 yards.

Exact same result was experienced as with the Gold Cup. Returned sight settings to their original locations.


C.) The sight was then mounted on a Ruger Mark II. Again, shooting two-handed, unsupported at 25 yards.

Same issue as before. Windage consistently way off, while elevation was very close with all three handguns.



LEUPOLD DELTAPOINT PRO:

Mounted on the Ruger SR-556FB. Shooting off of a bench at 100 Yards.

Windage required major changes to the left. Groups still 4 inches off. Stopped making furhter adjustments because sight was extremely close to running out of travel.

Elevation only required a few clicks to correct.



Is what I experienced considered to be normal? Must one go through some sort of "process" in order to get a usable sight? What is the failure rate of these things?

So far, one hundred percent of mine were "lemons". Is one manufacturer superior to all of the rest of them? What brand do you recommend? At 69, I need to use

optical sights, as my vision is not what it once was. When purchased years ago, all of the firearms mentioned above were easily zeroed with the iron sights that came

on them from the factory.

Reading several firearm magazines, it is apparent that dot sights are in vogue nowadays. However, I have noticed that so many shooters still keep back up iron sights

on their pistols and rifles. Initially puzzled by this practice, I now know why it is being resorted to! Your comments and advice are very much appreciated. Thank you.

Between my wife's bullseye pistols and my rifles and pistols, we have 8 we use regularly. 2 of hers and 1 of mine are mounted on 1911s. I have 4 ARs with them and one mounted on my 336 marlin. We have had no failures of any kind in the last 15 years or so, since we put them on. We have 5 ultradot, 2 bushnells and one vortex.

I have another 5 or 6 that have been on and off guns repeatedly over the last 15 years and no issues with any of those either.

I'm not sure what to give for advice since I'm not aware of anyone have much of an issue with them. I've played around with everything from super cheap milletts to high end trijicons and aim points on my duty guns and no issues at all.

No issues with my Burris FF3. I mounted it on a 10-22. Had to adjust windage and elevation to get it POI to equal POA. Then shot a couple relatively nice groups with it at 50 yds. I've since shot some steel with it a couple times and it's been great

I have a Vortex Viper that I bought on sale awhile back. I haven't mounted that one on anything yet

I've had multiples of Burris, Bushnell, Vortex, and ADE, a reliable budget brand. The only problem I ever had was one of them eating the battery too quickly. ADE customer service quickly rectified that problem. All have been reliable and accurate for years. Your unfortunate experience sounds like an outlier. The frustrating pattern seems like it might have a common cause other than red dots being universal lemons, but it's sufficiently foreign to me that I don't have any helpful suggestions.

I use primarily primary arms prism sights. None on rimfire akm in 7.62x39 or a couple on 5.56 akm. No problems. 3x 5x prism and a regular with no magnification on 9mm. Stribog sp9a3. Rimfire I use scopes. I had an extremely inexpensive reflex sight on a browning buckmark that did great. Sorry your experiencing problems.

My Holosun 507 on the Ruger Mk IV has been superb. The after-market mount had an issue with the screws not staying tight, but the LocTite brigade fixed 'em good. :)

That loose mount issue may be part of your problem. You didn't specify whether you'd checked, so forgive me if I seem to be teaching Grandma to suck eggs.

You were shooting to the left with all three handguns at 25 yards, and doing so unsupported.
Did you shoot them in off a bench beforehand, or just assume the dots were on and your shots should be on? They need zeroed the same as a scope.

Supposing you have a 3 MOA Dot. At 25 yards you should shoot it in rested on a bench using a 3/4''-1'' bull on your target. If you can hit the bull rested then move on to your off hand.
If your shooting to the left now, it's you fading to the left and not the fault of the red dot. Concentrate on not fading, keep the gun up and follow through.

As far as using a dot at 100 yards on a rifle, you will be lucky putting them in a 3" bull with a 3MOA dot.

I have Swamp Fox, Sig and 2 Holosuns on pistols. Very little adjustment required, shoots fine.

I have Sig, Vortex, PA, Holosun, Riton, TruGlo, Tacticon, Firefield, Monstrum, and Osight on AR’s. Dots and prisms. All were on paper when I started zeroing at 25 yards, all adjusted just fine, all will let me ring steel out to 300.

I mounted a super cheap cylee on a g44, required 2 clicks up, however that pistol itself is so inaccurate hard to say on holding zero. Most other mountings are on frame mounts which have offset and corrections were required. typically on slide mounts the 4 or so i've mounted required minimal adjustments for a 18-20yard zero.

One possibility you adjusted sights for your tendency to shoot left which as a right handed person is rather common.

I have been running red dots for a long time and never had the problems you are having. One gun I could understand but several guns and different dots tells me you are the problem. Have someone else sight in the guns and see if they have the same problem. Questions: Are you keeping both eyes open? Do you have an eye dominance problem?
My first red dot was a Weaver QuikPoint in the mid 60's.

It really doesn’t sound like there’s anything wrong with any of the sites you are using.

Having to use most of the available adjustment to achieve zero is fine as long as you are indeed able to get it zeroed.

Zeroing an unmagnified red dot at 100 yards is always going to be difficult and will probably eat up most of the available adjustments since they are usually used at much shorter distances. How much of the target is covered by dot at 100 yards? This is also why the range of adjustment is listed in the specs.
